If I was the manager I would have had a stern talk with my employees asking someone to do a burnout in my store customer's parking area. What if you lost control, crashed and burned.........I would think the store would be liable for damage you may have done to yourself and or the store property....If you had crashed I would bet a dollar to a donut hole you would say " hey, the parts guy(s) asked me to do a burn out..I just did what they asked me to do". So, a judge and your insurance company would look to the parts store to pay for your car, hospital bills, etc, punitive damages your Lawyer would think you and he would get in a lawsuit you, I am sure you would file........
Duhhhhh, think before you act for god's sake.........
